Effect of Impurities on Charging Track in the Performance of Wireless Capacitive Charging Technique

This paper presents an analysis of the effect of impurities on the performance of capacitive charging technique on electric vehicle; in this paper, commonly found impurities like sand, water and air are incorporated in the capacitive charging system. Impurities considered in the vicinity of plates have a thickness of 1, 3 and 5 mm. Finite element modelling (FEM) is performed for finding out the exact effect of the impurities in the system. COMSOL 5.2a is used for obtaining the result. The results obtained are reported and discussed in the paper.
